AIR CONDITIONER UNIT OPERATION
Dry Mode
When the air humidity is high, the unit can operate in
dry mode. Press <MODE> button and choose <DRY>.
If the room temperature is 2°C/3.6°F higher than the set
temperature, the air conditioner will operate under
cooling mode until it reaches within the 2°C/3.6°F range
of difference compared to the set temperature before it
converts to dry mode.
If the room temperature is within the 2°C/3.6°F range
of difference compared to the set temperature, it will
directly operate under dry mode.
The unit will operate at LOW speed under dry mode.
Heat Mode (for heat pump unit only)
When the unit is switched on from cold start or
defrosting cycle, the indoor fan will start to operate only
after the coil reaches the desired temperature.
When the set temperature is achieved, the indoor fan
will operate until the coil cannot provide anymore
additional heat.
Air Flow Control
For more effective air circulation, you can manually
adjust the air discharge grille to the left or right.
During cool mode operation and dry mode operation,
do not direct the air discharge louver downwards for too
long. If operating continues in this way, condensation
may occur on the louver, thus resulting in drippings.
Overheating Protection (for heat pump unit only)
In case the internal and/or the external temperature is
too high, or that the filter is dirty and clogged up, the
refrigerant may be overheated. The compressor will cut
out when the condensing temperature reaches 62°C/
143.6°F.
Frost Prevention
When the air filter is dirty, the evaporating temperature
will decrease and eventually cause frosting.
If the evaporating temperature reaches -1°C/33.8°F, the
unit will trip.
Fan Speed And Rated Cooling Capacity
The rated cooling capacity is provided at the HIGH fan
speed.
The cooling capacity is lower when the unit is operating
at MEDIUM and LOW fan speed.

Notes On Flaps And Louvers Angles
When “SWING button” is selected, the flaps swinging
range depends on the operation mode. (See the figure.)
ATTENTION
Always use a remote controller to adjust the flaps angle.
If you attempt to move it forcibly with hand when it
is swinging, the mechanism may be broken.
Be careful when adjusting the louvers. Inside the air
outlet, a fan is rotating at a high speed.
